How many injections are given in the HBV vaccination series?

The hepatitis B virus (HBV) vaccination series consists of three injections. This series is designed to ensure effective immunity against the virus, which can lead to serious health issues such as chronic liver disease and liver cancer. The standard schedule for the HBV vaccine includes the first dose, followed by a second dose typically one month later, and a final dose administered six months after the first. The three-dose series is necessary to achieve adequate and long-lasting immunity, making it an essential component of public health initiatives aimed at preventing HBV infections.
